Lithuania, with its rich tapestry of ancient forests, vast wetlands, and a pristine Baltic coastline, is a sanctuary for a wide array of wildlife. This diverse landscape supports a surprising variety of species, many of which are facing increasing pressures and are thus considered rare within the country’s borders.
In this compilation, you’ll discover 23 Rare Animals in Lithuania, representing a fascinating cross-section of its endangered biodiversity. From the delicate Aquatic warbler to the striking White‑backed woodpecker, this list highlights species that require special attention. For each, you’ll find below its Scientific Name, Rarity Status, and Main Habitat, offering a clear snapshot of their current situation.
Why are some animals considered rare in Lithuania?
The rarity of certain animal species in Lithuania is often a result of a combination of factors unique to its ecosystems. Habitat loss and fragmentation due to agricultural expansion, urbanization, and unsustainable forestry practices are primary concerns. Additionally, climate change impacts, pollution, and historical over-hunting or collecting have significantly reduced populations for many species. Some, like the Aquatic warbler, also have naturally specialized habitat requirements, making them more vulnerable to any environmental shifts.

Images and Descriptions
European mink
Small semi-aquatic mustelid with dark fur and a pale chin. Populations collapsed from habitat loss, pollution and competition with introduced American mink. Extremely rare in Lithuania, surviving only in fragmented wetland pockets and under strict protection programs.
European pond turtle
A shy fresh‑water turtle with a dark, oval shell. Declined sharply from wetland drainage, egg predation and habitat degradation. Survives in scattered ponds and oxbows; conservation focuses on protecting nesting sites and water quality.
European eel
Catadromous fish that migrates to the Sargasso Sea to spawn. Numbers have plunged from barriers, overfishing, pollution and disease. Found in Lithuanian rivers and coast; management targets restoring migration routes and reducing mortality.
Pond bat
Medium‑sized bat that forages low over water for moths. Requires mature riparian woodland and old buildings for roosts. Populations fell with wetland loss, disturbance and light pollution; now rare and legally protected in Lithuania.
Barbastelle
Dark, broad‑eared bat that roosts in tree cavities and old buildings. Extremely sensitive to forestry practices and fragmentation; small, scattered populations in Lithuania make it a conservation priority under national and EU protections.
European bison
Europe’s heaviest land mammal, reintroduced after extirpation. Live in small, managed herds in forest reserves. Nationally rare, dependent on habitat management, anti‑poaching measures and occasional supplementary feeding in harsh winters.
Black stork
Solitary, forest‑nesting stork that avoids humans and nests in tall trees above floodplain wetlands. Sparse breeder in Lithuania; declines from disturbance and wetland loss have made it nationally rare and strictly protected.
Corncrake
Secretive grassland bird with a rasping call, often hidden in tall vegetation. Declined due to agricultural intensification and earlier mowing. Conservation relies on delayed hay cutting and managed wet meadows to sustain breeding sites.
Lesser spotted eagle
Medium‑sized forest raptor that nests in mature woodlands near wetlands. Threatened by habitat loss, forestry change and collisions. Lithuania still hosts important breeding birds, but populations are declining and protected.
White‑backed woodpecker
Large woodpecker dependent on mature deciduous stands rich in deadwood for nesting and foraging. Declines with loss of veteran trees and forestry intensification; a flagship species for forest conservation in Lithuania.
Capercaillie
Large grouse known for dramatic male displays on leks. Requires extensive, undisturbed mature conifer forest and patchy ground cover. Populations dropped due to fragmentation, disturbance and predation; monitored and managed as a threatened species.
Black grouse
Ground‑dwelling bird needing a mix of open bogs, heath and young woodland. Sensitive to land‑use change and disturbance; Lithuanian populations are small and fragmented, making conservation of semi‑open habitats vital.
Great snipe
Elusive migratory wader with a striking aerial courtship display. Breeds in wet meadows and boggy pastures that have been drained or converted. Rare in Lithuania and subject to targeted habitat conservation.
Harbour porpoise (Baltic)
Small toothed cetacean occurring intermittently off the Lithuanian coast. The Baltic population is critically endangered from bycatch, underwater noise and pollution. Occasional sightings spur conservation and monitoring efforts in national waters.
Atlantic salmon
Iconic migratory fish that returns from the sea to spawn in freshwater. Populations fell from dams, river degradation and overfishing. Restoration focuses on improving river connectivity and spawning habitat in Lithuanian rivers.
Sea lamprey
Jawless, eel‑like fish that migrates between sea and rivers to spawn. Impacted by barriers, pollution and habitat loss. Rare in Lithuania’s rivers and included in restoration and protection measures to improve spawning runs.
Smooth snake
Small, secretive non‑venomous snake preferring dry sandy habitats and open woodlands. Threatened by habitat loss from afforestation, development and dune stabilization. Small, localized populations are protected under national conservation measures.
Natterjack toad
Distinctive yellow‑striped toad of coastal dunes and ephemeral pools. Declined when dunes were stabilized, drained or developed. Survives in isolated coastal pockets; conservation focuses on maintaining open sandy wetlands and breeding pools.
Grey long‑eared bat
Large‑eared insectivore that forages over meadows and uses tree roosts or buildings. Sensitive to loss of roost sites and foraging habitat; small and scattered Lithuanian populations receive legal protection and monitoring.
European wildcat
Solitary forest cat resembling a thick‑furred wild feline. Threats include habitat fragmentation, persecution and hybridization with feral cats. Populations in Lithuania are small and fragmented, protected under national wildlife laws.
Eurasian lynx
Elusive medium‑large predator dependent on extensive forest tracts and healthy ungulate prey. Populations are low regionally and strictly protected; lynx conservation requires large connected habitats and anti‑poaching enforcement.
Aquatic warbler
Europe’s rarest passerine, breeding in open, shallow mires and wet sedge vegetation. Threatened by drainage, succession and habitat loss. Lithuania hosts vital breeding sites and actively manages mires to support this species.
Brown bear
Large omnivore now a very rare resident or cross‑border visitor in Lithuania’s forested borderlands. Strictly protected; conservation depends on transboundary habitat connectivity, conflict mitigation and long‑term habitat protection.
